Hello doctor,

I have recently done a glucose tolerance test, where insulin levels were measured on 0 minutes, 60 minutes, and 120 minutes. The results are:

  • 0 Minute: Glucose 4.74 mmol/l, Insulin 11.2 uIU/ml.
  • 60 Minure: Glucose 8.71 mmol/l, Insulin 104.3 uIU/ml.
  • 120 Minute: Glucose 5.07 mmol/l, Insulin 13.16 uIU/ml.

I can see that the glucose is within normal reference numbers, but on 60th minute the insulin seems too high. Is it? What are the reference numbers for insulin on the 60th minute? Is this a sign of insulin resistance? What would you recommend as a treatment?



Welcome to icliniq.com.

I would like to see the image of your reports and would also like to know, have you undergone the HbA1c test. How long you have been diabetic, have you been on oral antidiabetics.

Hello doctor,

Thank you for your answer. I am attaching the image. I am not diabetic, at least I have not been diagnosed. I do not have a HbA1c test and I have not taken any medications so far.



Welcome back to icliniq.com.

I have seen your lipid profile test (attachment removed to protect patient identity), OGTT (oral glucose tolerance test), and insulin levels. Whatever is being reflected from the investigation reports you have sent me, we need to control your cholesterol level. Yes you seem to lie in IFG (impaired fasting glycemia) category.

Since you are in the high-risk category because of your deranged BMI (body mass index), you have a higher weight and need to achieve a target of at least 78 kg of weight in three months. That will help bring down your cholesterol, BMI and control your deranged blood sugar.

Just remember, you are a young chap, if you do not change your lifestyle now, it will lead to early onset of diabetes, obesity, and dyslipidemia. Therefore, I am starting you on an exercise regimen and only one medication to check and bring down your deranged parameters.

I suggest:

  • Thyroid profile (T3, T4, TSH, fT3, and fT4).
  • Brisk walk five days a week.
  • Tablet Rosuvastatin 5 mg once daily after lunch for four weeks.
  • Reduce oil and fats, stop junk food.

Follow up after four weeks with:

  1. Kidney function test.
  2. Liver function test.
  3. Lipid profile.
  4. Thyroid profile.
  5. Fasting blood sugar.
  6. Oral glucose tolerance test.
  7. HbA1c.
